• HCQ -
the incidence of retinal toxicity was only 0.95/1000 patient-years
majority of those with retinal toxicity were on HCQ for >5 years
and most used doses of >6.5 mg/kg
• AZA -
incidence of leukopenia or anaemia was 5 - 20%
abnormal LFTs requiring discontinuation of drug in 1 - 6%
• MTX -
LFT abnormalities ranged at 10 - 50%
• CYC -
incidence of leukopenia or anaemia was 5 - 10%
increased incidence of cervical dysplasia in patients taking CYC
compared with corticosteroids alone
• MMF -
incidence of haematological toxicity was 1.1 - 36.8%
• NSAIDs and salicylates -
most powerful predictor of gastric mucosal injury (OR=26.8,
95%CI 4.9 to 148.6)
reduced renal function by 58% and increased serum creatinine
by 163% in patients with active LN

A summary of current guidelines for laboratory monitoring as well as an
overview of laboratory abnormalities of each drug and recommendations
on frequency of monitoring are provided in the Appendix 7 and

A prospective cohort study on patients with inactive disease of SLE
showed that a clinic visit interval of 3.8 months was able to identify
